Testing
The next two weeks are going to be filled with long nights of testing, collecting data, tweaking, analyzing data, re-testing, et cetera. We’re running experiments to collect data for our FDA application for our Kahanu ventilator.
Jeffrey Hayashida and Micah Brodsky are leading the mechanical and respiratory tests. We are also finally starting to test with Peter How‘s custom-designed breathing circuit. He designed the Powerwall while he was at Tesla, and it’s cool to hear the connections between moving air to cool a box of hard-working batteries and moving air in very specific ways for respiratory care.
Mahalo to Kai Matthes for yet again donating last minute gear we need. Meanwhile, Micah scored us some borrowed high-end gear that we are using to supplement our homebrew test setups.
Here is a peek at one screen showing pre-noise filtered results from our first 1.6 million data points. We custom built this software to digest a bamboocha amount of data. If you have ever been part of an engineering project, you’ll recognize that the phases and skills needed to design and ultimately ship a product are so radically diverse.

Our daily calls are getting pretty hilarious. I wish we weren’t spread out by thousands of miles.
Which reminds me… we do ship tons of stuff to each other. Last week I tried to ship three ventilators to Jeff on Maui, and USPS said they were slightly too large to go by air, so it would take about month by barge. Yikes!
A short trip to the airport and they were on board air cargo later that day.
So many stories!
